The Serpentine Galleries have revealed that the 2016 Serpentine Pavilion will be designed by Bjarke Ingels Group (BIG), alongside a surprise announcement that four "Summer Houses" will also be built by internationally acclaimed practices. Kunlé Adeyemi – NLÉ (Amsterdam/Lagos), Barkow Leibinger (Berlin/New York), Yona Friedman (Paris), and Asif Khan (London) will each design a 25sqm structure inspired by the nearby Queen Caroline’s Temple, a neo-Classical summer house built in 1734 and "a stone’s throw from the Serpentine Gallery." In line with the criteria for the selection of the Serpentine Pavilion architect, each chosen to design a Summer House has yet to realise a permanent building in England.

According to the Serpentine Galleries, the expanded scheme will be submitted to Westminster City Council Planning Office and District Surveyor’s Office for planning later this month. The Serpentine Summer Houses, sited one minute’s walk from the Serpentine Gallery, "will complement the world-famous Pavilion commission on the Gallery’s lawn by offering visitors an unrivalled, first-hand experience of contemporary architecture by leading international architects from across the generations, within the historic parkland of Kensington Gardens."

After 15 years, the Pavilion programme has expanded. It now comprises five structures, each designed by an architect of international renown, aged between 36 and 93. The Pavilion, which will be situated on the lawn of the Serpentine Gallery, as usual, will be joined by four 25sqm Summer Houses designed in response to Queen Caroline’s Temple, a classical-style summer house built in 1734. All projects have been thrilling to commission and will be equally exciting to realise. We cannot wait to unveil them all this summer.

The selection of the architects, chosen for consistently extending the boundaries of architecture practice, is led by the Serpentine’s core curatorial thinking, introducing contemporary artists and architects to a wider audience. The brief is to design a 300-square-metre Pavilion that is used as a café by day and a forum for learning, debate and entertainment at night. Serpentine Galleries will be partnering with Harrods for the 2016 Pavilion Café.

The Serpentine's Pavilion commission, conceived in 2000 by Director Julia Peyton-Jones, has become an international site for architectural experimentation and has presented projects by some of the world's greatest architects. Each Pavilion is sited on the Serpentine Gallery's lawn for four months and the immediacy of the commission—taking a maximum of six months from invitation to completion—provides a unique model worldwide. There is no budget for the project, it is realised through sponsorship, help-in-kind support and the sale of the Pavilion.
